Core summary
Three Identical Triplets examines a real-life nature-versus-nurture investigation in which triplets separated at birth are reunited in young adulthood. The film documents their rapid bonding, shared mannerisms, and the ethical questions around the study that recruited them. Released in 2018, it blends personal story with scientific critique and remains an evergreen resource for understanding consent, environment, and family dynamics.
Background and origins
The documentary centers on the 1960s longitudinal study led by psychiatrist Peter B. Neubauer, who separated triplets—David Kellman, Eddy Galland, and Robert Shafran—shortly after birth and placed them with different working- and middle-class families. Each family believed they were adopting a single child and did not learn about the study until the three teenagers met in 1980. The chance reunion revealed striking similarities in personality, interests, and life events, prompting widespread attention and later scrutiny of the research methods.
Key subjects and narrative focus
The film foregrounds the voices and experiences of the triplets themselves, allowing them to describe their reunion, sense of connection, and the emotional journey of discovering shared history. It contextualizes the rapid bonding against the backdrop of their adoptive families’ environments and raises questions about how much of their likeness stemmed from genetics versus upbringing. The narrative also follows contemporaneous family members and includes commentary from researchers and journalists.
Context within documentary and research ethics
The study and its aims
Neubauer’s study intended to explore how personality and cognitive development are shaped by nature and nurture by placing twins and triplets into contrasting socioeconomic homes. The research was never published in a fully transparent or peer-reviewed form, and key ethical safeguards were absent, including informed consent from the children and, as adults, from the triplets themselves.
Media reception and impact
Upon release, the documentary was praised for its human focus and accessible explanation of complex scientific and ethical issues. Critics highlighted the need for responsible research involving children, emphasizing transparency and participant rights. Over time, the film has been referenced in discussions about institutional review boards, data sharing, and long-term follow-up with participants.
Audience takeaways and legacy
- Human dimension: The triplets’ candid reflections anchor a story of kinship, identity, and personal discovery.
- Ethical lens: The documentary underscores the necessity of informed consent, oversight, and accountability in longitudinal research.
- Ongoing relevance: It remains a touchstone for conversations about privacy, data use, and the responsibilities of institutions in research involving vulnerable populations.

Considerations for viewers
While the triplets’ reunion is emotionally compelling, audiences are encouraged to recognize the limitations and ethics of the underlying study. The film does not aim to present a comprehensive research report but rather to humanize the participants and illustrate the consequences of decisions made decades earlier. Continued discussion about research governance and participant rights reflects the documentary’s lasting educational value.
Frequently asked questions
- What is the central question of the documentary? The film investigates how genetics and upbringing contribute to personality and life outcomes, using the reunion of triplets separated at birth as a case study.
- Why was the research controversial? The study lacked informed consent, independent oversight, and transparent methodology, raising enduring concerns about ethical standards in behavioral research.
- Are the triplets still in contact? The film and subsequent coverage indicate ongoing relationships among the triplets, though they have largely maintained privacy about their personal lives.
- Has the study been published in full? Comprehensive findings from the original research have not been independently verified or published in peer-reviewed journals, limiting external validation.
- How is the film used today? It is frequently shown in courses on psychology, ethics, and research methods to illustrate the importance of participant rights and methodological rigor.
